Model WQC-24 -Water Quality Meter - Issue WQC-24-050225

The Model WQC-24 is the latest development in DKK-TOA’s range of multi-parameter water quality meters. The very latest technologies combined with more than 50 years experience have resulted in a compact, high performance and robust water quality monitoring system. The compact sensor probe can provide measurement of up to 11 parameters simultaneously out of a total of 17 available parameters. The instrument also features an interface port for connection to a Global Positioning System (GPS), Local Area Network (LAN), printer or other communication peripherals.

Features

pH Electrode with Easily Replaceable Chip Module

Multiple Parameter Combinations The sensor probe can measure up to 11 parameters out of 17 available (pH, ORP, DO, EC, Turbidity, Temperature, Salinity, Total dissolved solids, Specific gravity and Water depth plus Chlorophyll and Ions of NO3

-, Cl-, F-, Ca2+, K+, NH4

+).

Newly Developed High Performance SensorspH sensor is equipped with our “Strong” electrode and pressure compensator.New DO sensor is functional even under non-flowing conditions. Electrodes can be easily replaced using “chip” style components.

Compact Sensor Probe 45 mm outer diameter sensor probe fits into a 2-inch well (standard sensor module).

Robust Sensor Probe Sensor probe facilitates measurements as far as 100 meters below the water surface and up to a maximum pressure of 1 MPa (excluding ion sensors).Optional depth sensor enables measurement and collection of sensor depth information.

Data Logging Storage Capacity Exceeds One MonthBuilt-in memory stores measured data for 35 days of continuous measurements (based on measurement every 15 minutes or every hour for Chlorophyll measurement). The sensor module has its own internal memory and can be left disconnected from the meter section while continuing to measure and record data.

Interface Port Compatible with Global Positioning Systems (GPS)An interface port is provided as a standard feature for connection to GPS, Printer, LAN or other data communication peripherals (RS-232C).

PC Based Data Acquisition SoftwareOptional WQC-LOG software runs on any Windows® based personal computer. Measurement data can be saved to disk and/or exported to other applications (c,s,v, data format). Personal computer requires serial port or USB-serial port adapter.
